Schematics of randomly distributed CNTs in a representative cuboid.
Schematic of a typical CNT junction.
Calculated pseudo potential contact energy values vs. CNT-CNT distance, d. (a) Total potential energy as a function of d and d′ vdW . (b) Variation of total potential energy vs. d′ vdW at different distance d. (c) Variations of total potential energy and d′ vdW vs. distance d.
Variation of contact and intrinsic resistances vs. distance between CNTs at a junction. (a) MWCNT polymer composite and (b) SWCNT polymer composite.
Statistics of deformed CNT junctions in a percolating CNT network. The solid dots represent the total CNT junctions while the hollow dots represent the junctions formed by the radially deformed CNTs.
Total resistance of junctions vs. angle between two radial deformed CNTs at ε = 0.1.
Comparisons of electrical conductivity. (a) MWCNT and (b)SWCNT polymer composites. The dashed and solid lines represent the simulation results without and with considering the radial deformation of CNTs, respectively.
Tunneling effects with different rates of work function on electrical conductivity of (a) MWCNT and (b) SWCNT nanocomposites.
